Health officials are considering extending the eligibility for a second COVID-19 vaccine booster dose to people under 50 amid a steady rise in cases, with the United States seeing a threefold increase over the past month.

U.S. President Joe Biden on February 10 said mask requirements for children would likely to start to fall away given federal plans to begin vaccinating children under the age of 5, but said it was probably premature to drop COVID mask requirements entirely.

With COVID-19 cases still high nationwide, “now is not the moment” to drop mask mandates in schools and other public places, U.S. Centers for Disease Control and Prevention (CDC) Director Dr. Rochelle Walensky told Reuters on February 8.

The U.S. Centers for Disease Control and Prevention (CDC) on May 13 advised that fully vaccinated people do not need to wear masks outdoors and can avoid wearing them indoors in most places, updated guidance the agency said will allow life to begin to return to normal. Reuters lays out some of recent scientific evidence on which the CDC and Director Rochelle Walensky based their updated guidelines, including vaccine efficacy against virus variants, increased availability and a reduction in cases.

The U.S. Centers for Disease Control and Prevention (CDC) has not found a link between heart inflammation and Covid-19 vaccines, the agency’s Director Rochelle Walensky said on April 27.
